Abstract
The invention discloses a link rod locking device for a leakage testing machine. The link rod locking device comprises an air cylinder piston rod (1), a link rod (2), a connecting rod (3), a middle joint (5) and a transition section (4), wherein the air cylinder piston rod (1) drives one end of the link rod (2) to operate under the effect of an air source, the link rod (2) drives the connecting rod (3) to operate, the transition section (4) is respectively connected with the link rod (2), the middle joint (5) and a lower press rod (9), and the other end of the middle joint (5) is connected with a support frame (8) in fixed arrangement. A sealing element and a sealing tooling clamp are connected onto the lower press rod (9), so a workpiece is sealed, even when the air leakage of an air cylinder occurs, the air cylinder can be opened only through damaging components or fracturing shaft pins at each connecting part under the impact of detecting pressure, and the overheating processing intensity and the hardness of each component are very high. Therefore, the fracture phenomenon cannot occur, and the better sealing effect is reached.
Description
Technical field
The present invention relates to Wet-dry leak test technology in the leakage tester, be applicable to high pressure and the UHV (ultra-high voltage) leak test of automobile air conditioner compressor (vortex and piston type) workpiece.
Background technology
The leak test technology is to detect a kind of mode that foundry goods leaks, and can solve the follow-up leakage of the mixing work of doing over again that turns by leak test.Practical is to compress with cylinder, hydraulic cylinder now, and cylinder and hydraulic cylinder do not live at the situation lower seal of gas leakage or leakage, can produce leakage; Present technique is locked with the cylinder drivening rod, locks the exhaust hood that puts in place and can stop air inlet, by connecting rod effect locking, has played anti-loosening effect fully, can not leak during sealing.
Summary of the invention
Present technical sealing seals by hydraulic cylinder or cylinder band dynamic seal, in case cylinder leakage tester or hydraulic cylinder leakage situation occur, will become flexible during sealing, cause the defective phenomenon of leak test, and using the cylinder drivening rod to move, the present invention locks at the in-position back link, even cylinder leakage tester and can not becoming flexible, unless loosening situation linkage assembly fracture appears or leak test spare damaged, so loosening problem when fundamentally having solved detection.
In order to solve problems of the prior art, the technical solution used in the present invention is: a kind of leakage tester connecting bar locking device, it comprises cylinder piston rod 1, connecting rod 2, connecting link 3, indirect 5, transition segment 4, described cylinder piston rod 1 drives described connecting rod 2 one ends operation under the effect of source of the gas, described connecting rod 2 drives described connecting link 3 operations, described transition segment 4 is connected to described connecting link 2, indirect 5 and down-pressed pole 9, and described indirect 5 other ends link to each other with the support 8 of fixed in position.The described indirect 5 of one client link of described transition segment 4, connecting link 2, the other end of described transition segment 4 connects described down-pressed pole 9, connects the sealing frock anchor clamps on the described down-pressed pole 9.
Beneficial effect of the present invention: present technique compared with prior art sealing property is higher, and maneuverability is stronger, and to environment, the factor affecting such as the temperature of air and humidity there is no that the qualification rate of leak test spare is higher than gas circuit air-leakage detector.Enclosure-type can not occur because of the gas leakage of cylinder or hydraulic cylinder or leakage seal loosening, thereby the leakage situation occurs.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
As shown in Figure 1, connecting bar locking structural scheme of mechanism for the embodiment of the invention, cylinder piston rod 1 is drivening rod 2 operations under the effect of source of the gas, connecting rod 2 drives connecting link 3 operations, because thereby the support 8 fixing indirect 5 that drive are moved, transition segment 4, down-pressed pole 9 and indirect 5, the arrival certain position stops under the effect that makes down-pressed pole 9 operate in magnetic switch on the cylinder downwards thereby transition segment 4 connects, connect sealing frock fixture guide sleeve 6 on the down-pressed pole 9, thereby neck bush 7 and seal make Work piece sealing, even the pivot pin that must make each junction of opening that cylinder leakage tester is wanted under the impact of detected pressures ruptures or parts damages, each parts advances bakingout process intensity and hardness is very high, thereby can the fracture phenomenon, thereby reach good sealing effectiveness.
Although the present invention with preferred embodiment openly as above, they are not to limit the present invention, anyly are familiar with this skill person, in the spirit and scope that do not break away from the invention, certainly when making various changes or retouch, belong to equally the present invention's protection domain.Therefore protection scope of the present invention should with the application claim was defined is as the criterion.
